More than 30,000 runners are expected to participate in this year's St. Jude Country Music Marathon and 1/2 Marathon.
Each year more than 50% of participants travel to Nashville from out of state, giving the local economy a $40 million-plus boost.
Centennial Park on West End Avenue will once again be the start of the full and half marathon. Runners in both will cross the finish line at LP Field.
Runners looking to participate in the race can still do so by registering at the marathon's Health and Fitness Expo.
The expo, held at the Nashville Convention Center in downtown, continues through 7 p.m. Friday and will feature more than 100 exhibitors with the latest in sports apparel, health and nutritional information and more. It is free and open to the public.
The fee to sign up is $150.
